A little trick we are doing. Large first burnout as mentioned. Then just a quick burnout just to start to get smoke after the first break in burn out. Roll on out until it bites, but continue rolling up past the starting line (no longer spinning obviously) but picking up all of the fresh glue further out. My buddy is running consistant 7.60's in the quarter w/1.2 60's in his 68 Chevelle.
